BE NICE to the dealer and let them know that it should be a Priority #1 ,You will wait there till it's fixed ... Call first and let them know when to expect you..
Go to the Top Person if you don't get priority treatment ,Accept no level of runaround!
It should have been perfect when you picked it up...Give them the oportunity to make it right.
Hope it is something easily fixed .
Where is the leak at? PICTURES?
How bad is it, a drop a puddle seepage ? Maybe just a loose fitting ?A quick fix tighten a fitting and ride to the dealer to save them a hassle and let them assure all is OK and they reflash the system to get the warning light fixed and you are on your way ,Work With them on it ond it will pay dividens later on ...Just trying to help at this could be easy fix ,we hope Good luck.
